Air Handling Unit Cabinet with Integral Mounting and Drain Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air handling units face challenges with complex and time-consuming installation and component rearrangement due to the need for multiple brackets and supports, and the difficulty in removing and replacing components, especially when configuring for different orientations relative to gravity.
Innovation Solution
The air handling unit features interior cabinet walls with integral mounting features and a double-wall construction, including insulating materials like polyurethane foam, which reduces the need for additional brackets and supports, and incorporates integral drain pans and assembly channels for easy component placement and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple brackets and supports are used for component mounting, then structural stability is improved, but installation complexity and time increase
Solution Approach 1:
The patent combines multiple separate mounting brackets and supports into integral mounting features that are directly formed as part of the cabinet wall structure. This merging eliminates the need for separate components while maintaining structural stability for component retention.
Solution Approach 2:
The cabinet walls are designed with integral mounting features that serve multiple functions: providing structural support, enabling component retention, and facilitating installation. This multi-functionality reduces the overall number of components needed while maintaining stability.
2Adaptability or versatility
If multiple separate components are used for mounting, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
By integrating mounting features directly into the cabinet wall structure, the patent simplifies component removal and installation operations. The integral design eliminates complex assembly/disassembly of separate brackets while maintaining configuration flexibility through strategically placed mounting locations.
3Reliability
If separate drain pans are used, then functional reliability is improved, but device complexity increases
Solution Approach 1:
The patent integrates drain pan functionality directly into the cabinet wall structure, eliminating the need for separate drain pan components. This merging maintains drainage reliability through proper structural design while reducing the overall number of parts in the system.
